This is a conversation between a man and a woman.  Please note that she asks seven questions which he answered quite simply, and she is speechless after answering only two questions. 

Woman:   Do you play golf ? 
Man:   Yes

Woman: How many times a week?  
Man:  Usually about 3. 

Woman: How much do you pay per round? 
Man: Usually about $35 which includes lunch. (This is where it gets scary !) 

Woman:  And how long have you been playing? 
Man: About 20 years, I suppose 

Woman:  So a round  costs $35 and you have 3 rounds a week which puts your spending each month at about $450. In one year, it would be approximately $5400 correct? 
Man: Correct 

Woman: If in 1 year you spend $5400, not accounting for inflation, the past 20 years puts your spending at about  $108,000 correct? 
Man: Seems about right. 

Woman:  Do you know that if you didn’t play so much golf, that money could have been put in an interest savings account and after accounting for compound interest for the past 20 years, you could buy a new Ferrari? 

Man: Do you play golf? 
Woman:  No. 

Man:  Where’s your Ferrari?
